I am a dog trainer and that doesn't seem like normal behavior. She either has the beginning stages of an UTI or if she is spayed, spay incontinence. I am not for spaying but that is a different story. I would look up vitamin C as that helps acidify the bladder, killing the bacteria. My dog is 30-35 pounds and gets 2000 mg a day. You cannot over dose on Vitamin C. You can get a little bit of diarrhea, but then just lessen the amount. Helped mine and my neighbor's dog. Good luck with everything!!!
